Short description: Long-term water quality data for 56 sites in eight European countries have been used to assess freshwater responses to reductions in acid deposition at a large spatial scale. 
Long description: From 1980 onwards the majority (38 of 56) of sites showed significant decreasing trends in pollution-derived sulphate, while only two sites showed a significant increase. Nitrate had a much weaker and more varied pattern. A general reduction in surface water acid anion concentrations has led to increases in acid neutralising capacity but much of the improvement in runoff quality to date has been the result of decreasing ionic strength. Increases in acid neutralising capacity have been accompanied by increases in pH and decreases in aluminium, although fewer trends were significant. Increases in pH appear to have been limited in some areas by rising concentrations of organic acids. Overall the trend is towards recovery, although there is spatial variation, with recovery strongest in the Czech Republic and Slovakia, moderate in Scandinavia and the UK and weakest in Germany.
